Sensorless Vector Control of Bldc Using Extended Kalman Filter
This Paper mainly deals with the implementation of vector control technique using the brushless DC motor (BLDC). Generally tachogenerators, resolvers or incremental encoders are used to detect the speed. These sensors require careful mounting and alignment, and special attention is required with electrical noises. A speed sensor need additional space for mounting and maintenance and hence incre...
متن کاملSensorless Position Control of Stepper Motor Using Extended Kalman Filter
This paper describes simple position control of sensorless hybrid stepper motor (HSM). A mathematical model for hybrid stepper motor is derived using mechanical and electrical equations, which is used to estimate the position of the motor using Extended Kalman Filter (EKF). In position control, estimated value is compared with the reference position and when both coincide, the motor is held at ...
متن کاملSpeed Sensorless Vector Control of Induction Motor Using Extended Kalman Filter
A vector control of an induction motor by an estimated speed using an extended Kalman filter is proposed. With this method, the states are composed of stator current and rotor flux. The rotor speed is regarded as a parameter, and the composite states consist of the original states and the rotor speed. The extended Kalman filter is employed to identify the speed of an induction motor and rotor f...
متن کاملExtended Kalman Filter for Sensorless Fault Tolerant Vector Control of PMSM with stator resistance estimation
This paper aims to provide a high performance sensorless control based on an Extended Kalman Filter (EKF) applied to fault-tolerant PMSM drive system with statorresistance estimation. It proposes a fast method of fault switches detection in the power converters. The considered drive is composed of three phases PMSM and a four leg three phase’s inverter when the fourth is the redundant leg. Afte...
متن کاملSensorless Speed Control of Surface PMSM using DTC Control Based on Extended Kalman Filter
_ Speed control of permanent magnet synchronous motor (PMSM) using Direct Torque Control has rapid response and good static and dynamic performance but less accurate since current, torque and flux linkage wave forms contain big ripples. To overcome these disadvantages stator flux linkage and rotor speed are estimated using Extended Kalman Filter. Therefore, sensorless speed control of surface p...
